6 years ago @wuyajun19900627 Are ncnn and mace in seperated shared library? If so, this may be caused by openmp initialization conflict.

Two ways to avoid this:

6 years ago I'm not familiar with gradle, maybe use -L to specify where gradle can find ncnn?
Why do you link ncnn with mace anyway?

6 years ago @liyinhgqw It's job demand. We try to use "ncnn" to help to improve the face detection rate,since our training model is not that good.

6 years ago I tested "ncnn", it is excellent in face detection. My training model file has some problems on face detection(It doesn't work well sometimes). So I want to take advantage of "ncnn" to do the job of detecting faces.

6 years ago @wuyajun19900627 As an out-of-bound discussion, this is a Gradle build issue, which is not related to MACE or ncnn. So we can close it.
If there is still an issue after you build them into one shared library, fell free to reopen this.
Before you open an issue, please make sure you have tried the following steps:
